It had been a few years since my Aunt Katie could come home for a visit. Katie, or Kat as we call her, is the youngest of seven siblings and my mom's only sister. Kat always stays with us whenever she comes to town for a visit. She speaks her mind and often comes across as crass or flirty.

This trip, I have been the focus of her attention ever since she arrived. Maybe she thinks that I am fair game to her barbs now that I'm eighteen. It seems that everything she says to me is filled with razor-sharp quips and sexual innuendos. She's made me blush more than a few times in the past, but this time, I have been redfaced her whole visit.

The other thing that I've noticed differently about this visit is her display of cleavage. In the past, I would catch glimpses down her shirt whenever she bent over or her bra through the gaps in the buttons of her blouse. Now, her low-cut tops and half-unbuttoned blouses have put her girls on full display and have definitely caught my eye.

I know she was deliberately trying to get my attention when she bent over to pick something off the floor and suddenly snapped her head up to catch me in mid-peek. Her devilish smirk spoke volumes, even as she waved her finger at me, calling me a naughty boy.

It wasn't just her breasts that she was advertising. Now and again, she'd bend over, giving me a glimpse of her ass as well. All in all, she looked pretty good for someone twice my age. Not that thirty-six is old, mind you.

On the third night, Kat came to the living room to watch a movie in an oversized, button-down flannel shirt with the buttons half undone. Of course, she gave me an eyeful look at every chance she got, even bending over to let me know that she wasn't wearing any panties. I could see her curly brown bush peeking out the bottom of her shirt as she poured a glass of wine. The bottle was almost gone before the movie was half over. The more Kat drank, the handsier she got with me, and at some point, covering us under a blanket to conceal her wandering hands. Between the alcohol and her focus on the move, Mom was oblivious to what was happening.

Mom said that she was going to bed after a particularly steamy sex scene. "She's going to go masturbate," Kat whispered after Mom left the room. "Let's watch that again," she said as she reached for the remote, intentionally pressing her breasts into my shoulder. Kat backed the movie up to the beginning of the scene where the actor was sucking on the actress's nipples and dropped the remote onto my lap, revealing my erection. "I'll help you with this if you help me with that," Kat pointed at the screen. "I love having my nipples sucked like that. What do you say? Do you want to help your Aunty with that?"

Aunt Kat's hand moved stealthily under the blanket, rubbing my stiffy through my sweatpants. "Go ahead. You know you want to. You haven't been able to keep your eyes off of them since I arrived," she purred as she shrugged her shirt off of her shoulder to expose her left tit. Her larger nipple began to harden as I lowered my mouth to it. She held the back of my head, enticing me to partake in her incestuous desires. Kat squeezed my cock as she gave me a tuggy as I groped and sucked her titties. In the heat of the moment, it only took a few strokes for her to make me cum in my pants. "You should get cleaned up before that seeps through your underwear."

I bolted to the bathroom to wash up, hoping to rejoin Kat on the couch while she was still in the mood. I stripped from the waist down and wiped myself clean with tissues. I tossed my soiled underpants down the laundry chute and went to my bedroom for a clean pair. I darted, bottomless, down the hallway to my room, holding my sweats in front of me as I ran.

As I entered my room, Aunt Kat was leaning against the bureau, naked, with a sly smirk across her face, while she playfully bit her pinky finger. "Shhh," she whispered, her finger on her lips. "Listen, you can hear your mom's vibrator." In the quiet of the house, we could hear the whirring noise of Mom's vibrator changing pitch as she fucked herself silly with it. "I told you she was going to go masturbate," Kat giggled.

I closed the door behind me as I stood there ogling my Aunty's wares. Her large breast sagged slightly from her chest. Light brown areolas encircled the large pokey nipples that I had just been sucking. Kat's flat stomach, wide hips, and unkempt seventies bush beckoned me. I went to her and dropped to my knees to bury my face in her pussy.

Kat raised her right leg and draped it over my shoulder, giving me better access to her vagina. She grabbed the back of my head, pulling my face to her steamy slit. An intoxicating aroma of her scent filled my nostrils. The sweet flavor of honey dust coated my tongue as I dipped into her petals. Kat dug her fingernails into my scalp while she grabbed a handful of hair. She gound her cunt onto my face, growling, "Eat me!" through gritted teeth. "Ahhh, God. Eat me."

I slid my fingers into her as I lapped her clit, making her beg for more. Looking up through a tangle of curlies, I could see Kat sucking on one of her nipples while I serviced her twat. "Hmm. You are a naughty boy," Kat purred as she sank to her knees. "Lay back, sweetie.

"Please let me fuck you," I gasped every time she raised up to let me breathe.

"Not yet, sweetie. Not yet," she said as she pushed me onto my back and took my manhood into her mouth. We froze momentarily when we heard my mother's door open, and we stayed that way until the bathroom door closed. Kat used the opportunity to kneel between my legs, waiting to start sucking me again as soon as we heard Mom's door click shut. Kat took my cock into her mouth while she twisted her hand like she was revving a motorcycle throttle. It was incredible the way she tickled my dick with her tonsils. My aunt would bring me to the pinnacle of climax but pinched it off the base of my cock to delay satisfaction before starting again.

My soft, muted moans turned to panic when I lost control. "I'm gonna cum!" I said.

"Mmm," Kat moaned as I pumped a load of cum into my Aunty's mouth.

I could see the smile in her eyes as she gulped frantically to swallow down my load cum. "Ahhh. I love that taste," she whispered as her mouth came off of my cock. "Let's see what fun stuff we can dream up for tomorrow when your mom is at work. Good night, sweetie." Kat quietly slipped into the hallway and disappeared into the darkness.

I woke around six the next morning with my dick stuck to the bedsheets. I had crawled into bed with my dick still damp from my Aunty's blowjob. I decided to grab a shower before my mom had to get ready for work. Mom and Aunt Kat were in the kitchen making coffee by the time I finished in the bathroom. I tried to act normal when I went in for breakfast despite Aunt Kat started playing grab ass as soon as Mom went to get ready for work. "So? Did you have a wet dream about me and wake up all sticky, or did you wake up with morning wood?" Kat asked as she groped my crotch. "Come on and let your aunty see that cock of yours."

Not wanting to risk being caught by my mother, I brushed her hand away. "You're Psycho; Mom's in the next room! She'll kill us both if she catches us," I said, trying to keep her at bay. There was a flurry of hands as I swatted her hands away. As Kat chased me around the kitchen, her oversized sleep shirt fell off her shoulder again, letting me see her tit flop around as she chased me. She cornered me by the sink, giggling as she closed in on me. I reached out and copped a feel before ducking under her arm and running back to my room with Kat close behind. We got halfway down the hall when Mom stuck her head out of the bathroom, yelling for us to quit fucking around just as I slammed my bedroom door.

"You're too old for me not to take you over my knee," Kat shouted as she went back to the kitchen. I played on my phone until it was almost time for Mom to leave for work before coming out of my room. Kat was sitting at the table, sipping coffee and patiently waiting for the next opportunity to pounce on me. Kat had me pinned down on the living room carpet by the time Mom hit the end of the driveway. Her titties swayed back and forth while she tried to hold me down by my wrists. I stretched my next enough to suck one of her nipples into my mouth.

Kat eased her grip on me, allowing me to slip one hand free. I grabbed the back of her head and pulled her lips to mine. Kat's tongue darted into my mouth, tangling with mine as we kissed. She pressed her cunt against my growing erection, grinding on me as she sat up to remove her shirt. "What did you dream up for us today?" she asked sultrily.

I grabbed both of her breasts, telling her that I wanted to begin by fucking her gorgeous titties. "Let's go see if your mom has any lube."

Kat opened the bottom drawer of the nightstand and pulled out a tube of lube from amongst the plethora of toys. She got onto her back on Mom's bed and squirted some onto her cleavage, squealing that it was cold. Aunt Kat beckoned me with her finger, telling me to straddle her chest. She grabbed my cock and sucked a glob of precum off of it before she wedged it between her breasts. She slid them up in down the length of my cock, telling me to fuck her titties. Every couple of strokes, Kat would let the tip of my cock slip into her mouth for her to suck it.

Of all the girls that I've been with, I never got to tit fuck any of them. They either had small tits or wouldn't let me violate their breasts. I was definitely going to enjoy this. My cock made squishy sounds as it slid through her cleavage. Kay pinched her nipples as she pressed her tits tighter on my cock. As much as I wanted to savor this, the excitement was too much, and I blew my wad, squirting cum across her face. My aunt laughed as she tried to wrangle my cock into her mouth. A cum covered smile broke out on her face when I looked down upon her.

Kat slid her tongue up and down the vein as she sucked on the head of my cock, keeping me hard. "Do you think you have another one in you, cuz I'm not done yet?" I smiled back, telling her that I was young and I could do this all day, especially with my hot aunt. "We're both adults, and it's just a little harmless incestuous fun. Now get back there and give me a good pounding,'' she said as she got on her knees.

"Do you really want me sticking this in there? It's all covered with cum."

"You can bareback me as much as you want. I got fixed years ago," she pointed to the small scars on her abdomen.

"Barebacking my aunt Kat. What could be more fun?"

"Butt stuff, but that might be a little advanced for you." Kat's wicked grin spoke volumes.

"You'd be surprised. I'm a quick study."

"Maybe later, but for now, shove that big cock of yours in my cunt." Kat pointed to her behind with her thumb.

I positioned myself behind my aunt and slid my cock through her slippery slit, coating it with her juices before shoving it into her steamy hole. Kat leaned into me as I drove my cock home, letting out a loud hmph when I hit bottom. "You are a big boy, aren't you?" she giggled over her shoulder. I grabbed her hips and started to pound my meat as she had asked for. She was hot and ready, with no warm-up needed. All I had to do was hammer my cock up her snatch. My balls slapped against her muff with every powerful thrust, and I had Aunt Kat squealing within minutes of hammering her womb. "Fuck. That's it! Rearrange my guts, you motherfucker!" she wailed.

"Do you like my fat cock, Aunt Kat? Am I your naughty boy?"

"God, Yes! You're my naughty nephew! My favorite naughty nephew!" she cried out. "Harder! Fuck your Aunty harder!"

I increased the pace, pounding her vagina as fast as I could until I accidentally slipped out of her hole and bent my cock in half, causing us both momentary pain. I fell forward, pinning her to the bed as my cock slid back into her depth. I rolled us to the side so as not to crush her. Realizing that I could reach her pussy, I reached around her so I could rub her clit while I slammed my cock up her hole, making her squeal in ecstasy. She grabbed my ass cheek, begging for more.

I know she came a bunch of times before I pulled my cock out, and touched it to her sphincter, asked if she'd like it in her ass yet. "God, Yes!" she groaned as I pushed the tip in.

I put my hand under Kat's knee to hold it up as I slid my cock into her pucker while she crammed her fingers into her twat. "Ohh, God! That's it. Oh my fucking gaawd, fuck my ass, baby."

"What the fuck is that?" I asked when I suddenly felt a buzzing on my cock.

"Your mom's vibrator. It was under her pillow," Kat said as she pushed it into her pussy. "Oh, Fuck, Shit," she cried out as she worked herself over with the vibrator. "Hurry up, boy. I don't know how much more of this I can take!"

Not only did the toy make Aunt Kat's ass tighter, but the ass sensation of the vibrator pushed me over the brink. Just saying "I came" would be the understatement of the century. I came so hard that it felt like a fire hose trying unsuccessfully to extinguish her incestuous lust as I power-washed her insides. We lay there gasping for air in a convulsing heap as the last waves of climax withered away.

Kay's ass pucker clenched around the head of my cock as it fell limp from her backdoor. I laughed as the vibrator fell from her vagina as she waddled to the bathroom to clean up. I picked it up and followed Kat down the hall. I returned it after I washed it. I tucked the toy under her pillow and tried to leave Mom's room the way we found it so she wouldn't know what we had done before joining my aunt in the shower. Needless to say, Aunt Kat was walking bowlegged by the time she left.
